[To all whom, it concern/.

One object ofmy'invention is to effectimprovements' in the construction of the table: frames. a s r j v A further object of myinvention is to provideimproved means for locking the table- In'the accompanyingdrawings,Figure is an inverted plan View of a table embodying my improvements, the supporting-legs being the fr-ame being closed against each other to reduce the table to its smallest compass. Fig. 2 is a sectional view of the same, showing the table-frames partly extended. Figs. 3,4, and 5 are detail views. V 4 r i In the embodiment of my invention I construct the table-frame in three sections. The end sections are indicated at 1 and the intermediate section at 2. Each of the end sections comprises an outer bar 3, an inner bar 4, and a pair of end bars 5, properly secured together. Theintermediate section comprises a pair of parallel side bars 6 and a pair of end bars 7 To the ends of the intermediate section are secured side boards 8, which bear against the sides of the end sections 1 and are slidably related thereto, so that when the end section to enable the leaves to be placed between them the joints or open spaces between the end sections and the intermediate section are covered by the said side boards. On the central portionsof the bars 6 of the intermediate frame 2 are secured blocks 9 of suitable construction, having transverse openings Patented May 24, 1904.

9 by means ofset-screws. 11. The barsd of the end sections 1 are :provided with ,blocks 12, the said blocks being slidable on the said lock-rods and the said blocks 12 having openings through which; the lock-rods extend, en-

larged at their outer portions, as at 13, coilsprings 14, disposed on the lock-rods, being housed in-the said enlargements 13. At the ends; of the lock-rods are stops 15, which are hereshown as nuts screwed thereon.

openings 17 to receive them to strengthen the connections between the said end and intermediate frames when the end frames bean against the intermediate frame, as shown in Fig. 1.

Lock-plates 17 are provided with openings 18, through which the lock-rods 10 extend,

the size of said openingsbeing such that the said lock-plateswhen they are disposed obliquely'with reference'to the lock-rods impinge against the opposite sides of the lockrods, as shown in Fig. 2, so that the said lockplates are adapted to frictionally engage and 1 I firmly clamp said lock-rods. Each of the lockplates is hinged at its inner end, as at 19, to-

a plate 20, secured to the under side of the table-top, either by the means here'shown or end sections and the said operating-rods having their outer ends connected together in pairs by means of handle-yokes 25, whereby each pair of the operating:rods may be moved si, multaneously to cause the lock-plates to disengage-the lock-rods. The springs 14 bear against the lock-plates and keep the latter normally in an inclined or oblique position with reference to the lock-rods, and hence frictionally engage therewitl1,so that the lockplates and the lock-rods coact to lock the respective sections of the table-frame in any position in which they may be with respect to each other, whether the table he in its smallest compass or extended to any extent. Prior to readjusting the table by moving either of the end sections toward or from the intermediate section the handle-yoke 24: of the end section to be adjusted must first be moved manually to cause the lock-plates carriedd by the said end section to disengage the ro s.

The side-boards 8, which cover the spaces between the end and intermediate sections, also serve to support the leaves which may be placed between the said sections, as will be understood. To support the intermediate portions of the said leaves and to secure the requisite rigidity between the sections when the table is extended, I provide slide-irons 26 of suitable length and of suitable size and shape cross-sectionally, the end portions of which operate in guides 27, which are secured.

to the under side of the table-top between the bars 3 t of the end sections 1. The brackets 28 29 (shown in Fig. 1) serve for the attachment of supporting-legs for the table.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily apparent, it is thought, without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A table of the class described, having a plurality of relativelyadj ustahle sect-ions, lockrods fixed to one section and slidingly engaging the other sections, lock plates pivotally mounted on the slidable sections, and having openings to frictionally engage the lock-rods when said plates are in normal position, and means for moving the plates to cause the openings to clear the lock-rods.

2. A table of the class described, having a plurality of relatively ad j ustable sections, lockrods fixed to one section and slidingly engaging the other sections, lock plates pivotally mounted on the slidable sections and having openings to frictionally engage the lock-rods when said plates are in normal position,springs to move said lock-plates to engaging position, and means to move the plates in position to cause their openings to clear the lock-rods.

3. A table of the class described, having a pluralityof relatively adj ustable sections, locl rods attached to one section and slidably connected to another, pivotally-mountcd lock devices to engage said lock-rods to lock the sections when adjusted, springs to normally ongage said lock devices frictionally with the lock-rods, and means to disengage said lock devices from the lock-rods.

4. In a table of the class described, the combination of end sections and an intermediate section, lock-rods attached to the intermediate section and slidinglyconnected to the end sections, pivotally-mounted lock-plates carried by the end sections and having openings to frictionally engage the lock-rods, springs coacting with the lock-plates to engage the latter with the lock-rods, and means to turn the lock plates against the tension of the springs to the position required to disengage the lock-rods.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
